Sorry for the late reply, was out of the country on business.
I had purchased ~8-10 pairs of Oakleys at the time and was introduced to the Oakley sales rep (this was in roughly 2004). He asked if I would be interested in a new design for prescription lenses...I accepted the offer and at the time it was listed on my receipt as "Astor 101". I'm not sure if they eventually evolved into something on the Why line.
I still have all of the Oakleys for sale as I only received messages/PM's (except for SpliceD who I just replied to) with questions prior to my travel.
